The Chandler Fire Department responded to the first-alarm fire at the southeast corner of Arizona Avenue and Boston Street shortly after 11 a.m.

The fire was burning through the roof of a building housing adjacent restaurants La Bocca Urban Kitchen + Wine Bar and Modern Margarita, which opened in 2016 in the heart of downtown Chandler, fire officials said.

Battalion Chief Blas Minor said most of the damage occurred in a kitchen shared by the two restaurants. Fire crews had to cut multiple holes in the building's roof to gain access, he said.

Chandler fire officials tweeted out a video showing firefighters on the roof of the building with smoke breaking through.

One of the restaurants was preparing to open when the fire started, Minor added.
